Pseudotumor vermis Pseudotumor vermis is an aberrant CT finding that can be misinterpreted as early medulloblastoma Normal gray matter of cerebellar vermis (median portion of cerebellum) at times will enhance with contrast medium, simulating early medulloblastoma on CT scan Selective viewing of MRI scan will distinguish physiologic pseudotumor vermis from pathologic medulloblastoma
5 Interesting Facts of Cyanotic congenital heart disease Usually presents with acute onset of cyanosis around the time of ductal closure in the neonatal period, usually 2 to 3 days after birth In contrast with meconium aspiration syndrome, most neonates with cyanotic congenital heart disease present with relatively comfortable tachypnea (without retractions) and cardiac murmurs …
Delayed transition from fetal circulation Rapid transition from fetal life to neonatal life is a complex adaption process involving rapid pulmonary changes (eg, clearance of lung fluid, surfactant secretion, decrease in pulmonary vascular resistance, increase in pulmonary blood flow), cardiovascular changes (transition from fetal to neonatal cardiovascular circulation), endocrine changes, and central nervous system changes …
6 Interesting Facts of Infant respiratory distress syndrome Caused by surfactant deficiency and almost exclusively a disease of preterm infants Risk of syndrome increases with decreasing gestational age (5% of near-term infants, 30% of infants at less than 30 weeks of gestation, and 60% of infants at less than 28 weeks of gestation are affected) …
Breast abscess Localized collection of pus in the dermis or subcutaneous tissue of the breast Often follows mastitis Signs and symptoms of mastitis and abscess overlap because both of these infections often occur over a spectrum Occurs in both lactating women (14%) and nonlactating women (86%) If diagnosis is unclear, ultrasonography-assisted fluid collection can help …
Plugged milk duct Stasis of milk in the duct usually caused by ineffective feeding or local pressure from constrictive clothing in lactating women Although there is unilateral focal swelling and tenderness, there is no fever, warmth, or erythema Onset is more gradual than in mastitis and symptoms occur after feedings When treated with warm packs, …
Familial thoracic aortic aneurysm and dissection syndrome Cardiovascular disorder with autosomal dominant transmission presents with aortic disease similar to that of Marfan syndrome, but with no other phenotypic abnormalities associated with marfanoid syndromes 3 variants of the disease are recognized: one without other cardiovascular abnormalities, another with associated bicuspid aortic valve, and a third with …
